I'm not sure why this happens yet though. My solution is to clear both copies of the texture (which is probably a sane configuration anyway).
It looks like the texture cache is cleared correctly, but the texture is instead uploaded from memory again (where it wasn't cleared). + Nintendo and Sora Ltd as well as Bandai Namco Games (and Daddy Sakurai) for Sm4sh Bros for Lucinas hairstyles + SsbbNessFans XNALara model of Lucina via Deviantart. Its time to challenge our fate and change it by savescumming.
I'm not going to integrate it probably as I don't know if it causes regressions and I'm not sure how to best convert between texture formats. Fire Emblem Awakening is a title that, retroactively, is not only regarded as one of the best Fire Emblem games ever created, but as one of the best 3DS games ever released. I do have a working solution but it's pretty slow and hacky code. Earlier today, I've been investigating why Pokemon outlines fail.
